REGENERATIVE COKE-OVEN. v

To allowlwm it may concern: l

Be it known that I, NICHOLAS Sonus'rnn, subject of the AEmperor of Germany, resid ing at 7 Princes street, in the city 'of Vestminster, London, England, have inventedcertain new and useful Improvements in Regenerative Coke-Ovens, and of which the following is a specification.

' This invention relates to coke ovens of the regenerative type, in which the regenerative ,tunnels are formed 1n the base of the structure, andthe objects of the invention are to so constructthe regenerative tunnels and so connect the same with the various flues and passages of the structure in the manner hereafter described, that equal heating of the I formed between the tunnel chambers and those passages which alternatively serve as exit fines for the products of combustion and air inlet passages, so that the products of combustion pass from one heating chamber in the side wall dividing two ovens, into one chamber of a tunnel forming one of a pair, while the products of combustion form the heating chamber Vin the next vside wall pass into one chamber of the other'tunnel of the pair. With respect to the other pair of tunnels, thc corresponding chambers of these are similarly connected with half of the number of the heating flues in corresponding side walls dividing the ovens so as to eitherl supply heated air thereto or to carry off' products of combustion.

The invention will be described with reference to the accompanying drawings.

Figure 1 is a longitudinal section of the right hand half of the structure, this section being taken through the heating flues in one of theside walls between two ovens, and Fig. 1^ shows the left hand half of the same coke oven, this section being taken through the adjacent colcing chamber. Fig. 2 is a transverse vertical section of the structure taken about the line X-Y of Fig. 1A and drawn to a slightly larger scale than the lat 4ipecitieatioii of Letters Patent.

terA figure. Fig. 3 is a horizontal section talfen about the line K1A-Y1 of E ig. 2. 'Fig 4 is av horizontal section through the regen:

erators and tunnels 19 and 20.

Referring to the drawings, in the base of the structure below the cokingichambers 1 and extending transversely relativelyfthereto, are built two pairs of regenerative tunnels 2, 3 and 4, 5, and each pair of regenera tive tunnels are similarly divided bmtransverse walls into regenerative chambers; thus the tunnel 2 is divided by the transversaux walls 6 as'shown in full lines at Fig. 2 and by dotted lines at Fig. 3, whilerthe other tunnel 3 completing the pair is divided by the walls 7 which are intermediate vin the plan view between the walls 6 of the tunnel 2. The other pair of iegenerative`tunnels 4,

5 are similarly divided as will be observed by an inspection of the drawings. All these chambers in the `tunnels are fitted with checker brick work as is usual.`

The side walls of the coking chambers v1 are each formed with ahe'ating chamber 8 vdivided in the example shown -into vertical heating ues 9, Fig. 1, and each heatingfluev 9 communicates at its base with a gas supply passage or passages 10 into which gays passes from'a main l1 through a pipe l2 controlled by'a cock or cocks 13, and the gas supply passage or passages 10, shownin vfull lines at Fig, l, extendsl through half the.

length of the side wall and supplies half the number of heating flues 9 in that heating chamber, while an exactly similar gas supply system supplies the other half of the number of heating flues 9 in the same side wall, and

when gas is admitted, by for instance the gas supply system shown in full lines at.v Fig.

,-1, to half the number of heating fines in the side wall, the gas supply system for the other halfof the fines in that side wall closed by the cock or Vcocks 13.

Beneath the sole of each coking chamber 1 and extending parallel therewith is a passage 14 divided centrally of its length, and half the number of vertical heating flues 9 in onoside wall communicate by base passages. 15 with one part of their corresponding passage 14, and the other half of the vertical heating fines 9 in that side wall communi cate with the other part of the corresponding divided passage 14, by v:similar passages 15.

Considering the left hand portion of thevertical section at Fig. 1^, that part of the passage 11 there shown in t'ull lines, comuninicates by a passage 1li with the upper part of one. of the regenerative chambers in the tunnel 2, while the next similar passage 1l, beneath the next cokiug chamber, communicates by a passage 17 with the upper part otl a chamber in the regenerative tunnel il. Each regenerative chamber of the tunnel '2 communicates by a passage 1H. and each regenerative chamber ot' the tunnel 3 communicates by a passageil, with a waste heat i'lue 1f), which can be connected by any suitable or vwcll known danipers, valves or the like either with. the main uptake for the products of combustion, or with the open air, as may be required` The other pair of regenerative tunnelsl 4, 5 are similari)v arranged and connected, with the waste heat flue 2O and with theparts of ythe passages 1+ extending half the width of the structure alioi'e the said tunnels l,

21 and 2; are regulating valves `governing the passages 1S, 18X from the regenerative chambers of' the tunnels to the waste heat llues 19, Q0.

23 are air passages, Figs. 2 and 3, extending entirely through the structure upon each side and parallel with the gas passages 10. 'l`he provision of such passages alid the construction of the gas passages forni the subject matter of my patent application No. 878,420, of even date herewith, and therefore are not further dealt with in this specification.

The description ot' the invention will be rendered more complete by describing the course of the products when the ovens are in operation. Considering Figs. 1 and 1^ ot the drawings, it will he assumed that gas is being supplied through the gas passages 1() on the right hand side ol" the drawing Fig. l, and coiisequently the il'teen vertical heating [lues 9 in the hall of tlie structure l"ig. l shown by way of example, are being supplied with gas. Simultaneously the waste heat liuc 20, Fig. 1. is open to the atmosphere and air passes b v the passages 1S,

18* to all the chambersv otl thel regenerative" tunnels l, 5, which tunnels are in a heated condition by products of combustion having previously passed through them. The air so admitted becomes heated by passing through the checker brick work in the chambers of the regenerative tunnels 4, 5, and the heated air passes through passages 16", Fig. El, from adjacent chambers of the tunnel 5 to alternate passages 14 beneath the right hand half` of the structure shown at Fi". 1, while heated air passes by passages 1% from adjacent chambers of the regenerative tunnel 4to the remaining passages 14 beneath the right hand half of the structure Fig. 1, so

that one'fpassage 14 beneath the right hand hail' of the structure, Fig. 1, is supplied with heated air from one chamber of a tunnel, such as i, while. the next passage 11 is supplied with heated air t'i'oni a chamber of the other tunnel 5 of the pair. Heated air passes from the passages 1-1 in the right half ot the structure through the passages 15 to the base ol' the heating tlues 9, where the air and gas commingle and combustion takes place. The products of combustion pass in' the direction ofthe arrows Fig. l, to tlieji left hand halt', Fig. 1^, where they pass" down the vertical heating flues in the )aid lett hand halt` and so by way of the passages 15 into the passages 1-1, and from thence by the passages 16 and 1T to the upper parts of the regenerative chambers in the pair of tunnels 2, 3, from whence the products of combustion pass away by the passages 1S. 18* to the waste heatflue 19, which at this time is in connection with the main uptake. Obviously when the waste heat flue 19 is disconnected from the uptake and open to the atmosphere. while the waste heat flue 2() is' connected to the uptake, and also the gas supply cocks 13 ou their-ight 90 hand side of Fig. 1, are closed, and those onl the left hand side. Fig. 1^, opened, the flow of the gas will be reversed.

By this invention I am enabled to provide regenerative chambers of considerable cubical capacity and length for-'each of the heating chambers of the side walls, whereas if instead of the pairs of regenerative tunnels so outlined` two single regenerative tunnels were employed, the same length of regenerative chamber and cubical capacity ot' same could not be allowed without weakening the structure, .introducing unequal heating of the substructure and greatly increasing the depth of the substructure.
